SPECIFICATION forming part of Letters Patent No. 656,135, dated August 14, 1900.

Application filed May 11, 1900.

To all whom it may concern: 7

Be it known that I, HENRY H. HAMLETT, a citizen of the United States, and a resident of Providence, in the State of Rhode Island, have invented a new and usefullmprovement in Hammering-Presses, of which the following is a specification.

The nature of my invention consists in the improved construction and arrangement of parts, whereby a conveniently-operated hammering-press is produced, as hereinafter fully set forth.

In the accompanying drawings, Figure 1 represents a front elevation of a hammeringpress embodying my improvement. Fig. 2 represents a side elevation of the same. Fig. 3 represents a vertical section taken in the line 3 3 of Fig. 1.

In the drawings, A represents the frame of the press,B the anvil,and O the hammer,which projects from the sliding hammer-bar D, held in the frame A and actuated in the downward direction by means of the spiral springs E E, arranged in the longitudinal perforations F F of the hammer-bar, the said springs being attached at their lower ends to the fixed eyes G G and at their upper ends to the cap H, which is secured to the end of the hammerbar D, and the rear side of the said hammerbar is provided with the notch I. At the back of the hammer-bar D is placed the sliding catch-bar J, provided with the pivoted catch K, the upper end of which is pressed forward by means of the spiral spring L, and to the frame A at the back of the sliding catch-bar J is placed the catch-deflector .W, pivoted to the frame A at the point M and actuated for adjustment at its lower end by means of the screw N, the said deflector being provided with the incline O, which upon theupward movement of the sliding catchbar J will cause the disengagement of the catch K from the notch I of the hammer-bar, thus allowing the action of the springs E E to cause the rapid downward movement of the hammer-bar and hammer, and the outward or inward adjustment of the catch-deflector W will serve to either increase or decrease the stroke of the hammer. The catch-bar J is operated by means of the hand-lever P, pivoted for sliding movement upon the stud Q, and upon the inner side of the leverP, upon Serial No. 16,370. (No model.)

the stud Q, is placed the spiral spring R, which is adapted to force the lever P outwardly upon the pivot-stud Q. The end of the lever P is connected with the catch-bar J by means of the arm S and link T, and to the side of the frameA is secured the guide V, provided with a notch U, into which by means of the spring R the lever P will be caused to pass at its downward movement, the said notch serving to hold the hammer in an elevated position above the anvil, in which retained position the hammer and anvil dies may be changed and adjusted as desired, the inward movement of the outer end of the lever P by the operator serving to cause its disengagement from the retaining-notch V, after which the lever P may be raised to allow the hammer to move slowly down to its seat upon the anvil, or the lever P may be depressed from its retained position until the catch K is forced out of the notch V, and then the hammer G will be brought down to the anvil with the full force of the springs E E.

I claim as my invention- 1. The combination of the anvil, the hammer and the sliding hammer-bar with the actuating-spring held in the longitudinal cavity of the hammer-bar, the operating-lever, the sliding catch-bar connected with the operating-lever, the catch pivoted to the sliding catch-bar, and adapted to engage with the hammer-bar, the pivoted catch-deflector and means for adjusting the catch-deflector to vary the stroke of the hammer, substantially as described.

2. The combination of the anvil, the hamm'er, and the sliding hammer-bar, with the actuating-spring held in the longitudinal cavity of the hammerbar, the operating-lever, the spring and notch for holding the said lever and hammer-bar in an intermediate position, the sliding catch-bar connected with the operating-lever, the catch pivoted to the sliding catch-bar and adapted to engage with the hammer-bar, and the catch-deflector for releasing the catch from the hammer-bar, sub- 'stantially as described.

HENRY I-I. HAMLETT.
